(Children's Hospital Los Angeles) A team of investigators at CHLA designed basic research studies to look at the effects of dinutuximab and activated natural killer cells on recurrent disease and overall survival in neuroblastoma. This research provided proof-of-concept for an upcoming clinical trial.

Mutations in the Anaplastic lymphoma tyrosine kinase (ALK) gene are common in NB. To study the contribution of ALK mutations in NB initiation and progression, we reprogrammed fibroblasts from two related NB patients carrying germline mutations in ALK (R1275Q) using non-integrating Sendai virus. The iPS cells are grown in a feeder- and ...

Abstract
Neuroblastoma is a neural crest-derived tumor that accounts for 7-10% of all malignancies in children and ~15% of all childhood cancer-associated mortalities. Approximately 50% of patients are characterized as high-risk (HR) and have an overall survival of

Adrenocortical carcinoma (ACC) and pheochromocytoma and paraganglioma (PPGL) are defined by clinicopathological criteria and can be further sub-divided based on different molecular features. Whether differences between these molecular subgroups are significant enough to re-challenge their current clinicopathological classification is currently unknown. It is also not fully understood to which other cancers ACC and PPGL show similarity to. To address these questions, we included recent RNA-Seq data from the Cancer Genome Atlas (TCGA) and Therapeutically Applicable Research to Generate Effective Tr...

This study was conducted to measure the association of XPA polymorphisms with neuroblastoma susceptibility in Chinese children. In this hospital-based case-control study with 393 cases and 812 controls, we genotyped two polymorphisms (rs1800975 T>C, and rs3176752 G>T) in XPA gene to access their contributions to neuroblastoma risk by TaqMan methods. The strength of the association with neuroblastoma risk was estimated by odds ratios (ORs) and 95% confidence intervals (CIs). No single polymorphism was found to predispose to neuroblastoma susceptibility. When risk genotypes were combined, we found that carriers of 1-2 ...

Neuroblastoma is a lethal tumor of the sympathetic nervous system. 8-Hydroxydeoxyguanine (8-OH-dG) formation is a common seen type of oxidative DNA damage, which could be repaired by human oxoguanine glycosylase 1 (hOGG1). To explore the contributing role of hOGG1 gene single nucleotide polymorphisms (SNPs) in neuroblastoma risk, we performed a case-control study by genotyping three SNPs (rs1052133 G>C, rs159153 T>C, rs293795 A>G) in hOGG1 gene. A total of 512 neuroblastoma cases and 1076 cancer-free controls were enrolled from three medical centers in China. The hOGG1 gene polymorphisms were determined using TaqM...

This study assessed the effects of the selective GLUT1 inhibitor WZB117 on regulation of neuroblastoma (NB) cell line SH-SY5Y viability, cell cycle and glycolysis in vitro. SH-SY5Y cells were grown and treated with WZB117 for up to 72 h and then subjected to cell viability, qRT-PCR, Western blot and flow cytometry analysis. Level of ATP and LDH was also analyzed. The result showed that WZB117 treatment reduced tumor cells viability, downregulated level of GLUT1 protein. Moreover, WZB117 treatment arrested tumor cells at the G0-G1 phase of the cell cycle, induced tumor cells to undergo necrosis instead of apoptosis. In ad...
